Resideo DB7110U1000 Universal Defrost Control Board Single-Stage Heat Pumps

The Resideo DB7110U1000 is a universal control board that enhances the defrost cycle of single-stage heat pumps. This component controls the outside unit’s compressor, reversing valve, and fan by the thermostat settings and the actual temperature obtained by the integrated sensors. It employs a demand defrost algorithm that means that defrost cycles are only called for when needed hence saving power and prolonging the life of equipment. This board is suitable for most single-stage heat pump systems and it is easy to operate. The DB7110U1000's capacity to operate in a variety of conditions (-40°F to 150°F) and endure fluctuating humidity levels assures consistent performance throughout the year.
